A key thing that's missing are more nodes. There is currently only one node that steem-engine.com is pulling from. That's not the end of the world because all the data is verified by Steem Witnesses on the Steem blockchain and anyone can run a node to see we're acting honestly, but it sure would be better if there were other nodes and the people operating them were all incentivized to witness blocks. Well, that's what we're doing. It's modeled after Steem, so it should be really familiar to people. We'll have a rotating set of witnesses that help assemble our chain. We expect our testnet to be up shortly after HF21 is implemented (end of August).

...this is awesome! Great news!! Are the requirements for running one of your nodes the same as being a regular Steem witness?

Congrats on the one million - y'all are really one of the best projects on Steem!
